The constant compiling of MathJax while composing a post is undesirable for me. How can I stop the MathJax preview?
Is there a way to turn off the MathJax preview?
Where is the button to switch off MathJax while typing a post?
There is no official feature for this (while it used to be present until mid-2013). For reports about this see Where is the off switch for the concurrent preview now?
However, it is possible to get this functionality using bookmarklets (for further details see below).
To pause it:
To turn it back on:
Create two bookmarks or favorites (or whatever your browser calls the functionality to save the address of some website), call them for example "MathJax: Off" and "MathJax: On".
Copy the line of code
When you want to stop MathJax, bring up your bookmark list (if you do not show it by default) and click "MathJax: Off"
When you want to restart MathJax do the same for "MathJax: On" Note that rendering might not start instantly. Possibly add some more characters to the post to get it started.
